This is why I don't trust Canon repair

Y'all might remember that I went through nearly a year of trying to get my 1 DX fixed. Never did. A few days ago Canon had a tent at the Phoenix Zoo and were showing off some new product. So I wondered by. I mentioned my difficulty with the 1Dx, which by chance I had been shooting that day. One of the fellows asked to look at it. He inquired if it had failed that day, and frankly I hadn't looked (as I've sort of learned to not bother). He looked back through my pictures and claimed they were all "perfect." Another fellow also looked and claimed them to all be "perfect."
These are two images they called "perfect." Notice they were both shot at exactly the same settings, but look at the difference. (These are undeveloped RAW converted to jpeg in LR.) I guess if that's what they call perfect, then my camera has no problems (which is what they claim!). There were about 6 more just like these that would have been some of the first they looked at.

Curious. Both seem to be exposed with the same settings, but the results are quite different.

Strange. The only thing to come to mind is if it was spot metering and the meter point is different from one to the other.

Are you able to determine exactly where the camera focused on each shot? Depending on how small the focal point is, could one have been on a darker spot than the other(no pun intended)? I see the sun glistening off the giraffe's back in the brighter image. Perhaps that is what the camera metered off in the darker shot.
Just a guess. You say it's not the only time it's happened, so I could be way off base.
I occasionally have similar results with my Nikon 750, but I always assume user error.

When this happens, look quickly to see if perhaps bracketing is turned on. I know that it is possible to set any of my cameras to take a set of two bracketed images, and it is also possible to set a fairly large exposure jump. Even if you are confident that this is not something that you are doing, it is possible that your camera has a failed (or failing) switch that it is causing it to do something that you do not want it to do.

I don't think it's bracketing or metering because the Exif shows identical settings. I think the possibility that the light changes between the 2 frames but it's unlikely. Of course the 2 images are JPEG and could it be that the conversion from raw to JPEG are different although the 2 images are the same?

That's my whole point! That is what that camera has been doing all along. And they say there's nothing wrong?

It wasn't spot metering, and they were taken just a couple of seconds apart. The camera simply doesn't meter correctly about 1/3 of the time.

Since this was part of a burst, the focusing didn't change. That's what it usually does that Canon supposedly "fixed" for a LOT of money. (and didn't fix at all)

That was the first thing I looked at when the camera first started doing this. It is turned off. I'm certain that the camera has a failure of some sort, but after sending it in four times to Canon repair and getting nowhere, I simply know that I have to take about 10 images to get a couple of good ones! Obviously, they think there is nothing wrong with it.

I don't see how the light could change in a couple of seconds. And since the conversions were both done exactly the same, nothing would have happened there. This is just one example of a frequent occurrence with this camera. I don't expect people here to "fix" it - mostly I'm just ranting. And having two Canon guys tell me just a few days ago that they didn't see anything "wrong," just convinced me that their repair service isn't worth much.

Not sure about the nomenclature, but basically it's set to an evaluative metering, not spot metering.
