I am really confused.

Applied lens correction (Nikon 70-200 2.8) and the image became brighter. To my simple brain this means that the exposure is being altered but the readings in the basic panel seemed to stay the same .

Please help reset my sanity and explain what is going on .

Here's a pretty good article on lens correction https://photographylife.com/lightroom-lens-corrections
The adjustments made by this contain, among other things, vignetting compensation. This will inherently brighten the image, especially the corners and edges, to a lesser degree. Thus, the image may appear a bit brighter without any input from you.

The brightness you see is sometimes due to a vignetting effect the lens may have. When corrected the vinetting goes away and the overall image may appear brighter. It happen with the Canon 24-105mm Mark I L lens too. I sometimes let the correction takes place sometimes not, depending on the image.

I learned that Lens Correction is the first filter applied in the Develop Module before everything else.

Hi Bob,

Many thanks, you have restored my sanity. The article is very interesting, just did not have the sense to realise it was the vignetting that was effecting it.

Now I understand, its tempting to leave the correction out . I'm making the correction then applying a vignette in some cases. Fell ever so slightly mad.

That is exactly what I was told , it makes sense but why do it at all if you are happy with the photo. Having read article referred to by Bob above I am going to apply the correction filter on import and then decided on any vignette.
