D7200 Resolution Dilemma

My Nikon D7000 bit the dust after several years of wonderful performance. Nikon wanted $300 to fix it but they had a D7200 refurbished for sale for $670 including tax and shipment. My D7000 was refurbished by Nikon and was a really good camera. The D7200 has 50% more pixels and no low pass filter (whatever that is). These two facts were supposed to result in better resolution. Right? The first few pictures were not noticeably better than what I was used to so I decided to run some tests. I had previously tested a couple of lenses on the D7000. What do you know? The tests don’t look any different to my old eyes. Shouldn’t the D7200 tests shots look noticeably better?
Here are just two of the test shots for you to consider. I will appreciate any help you can give me.
_REK0049 D7200 f/8 40 mm Micro
_REK3499 D7000 f/8 40 mm Micro
Any ideas? Should I send it back?

Are you comparing at a 1:1 ratio? That is where you will see a difference.

Exactly -

Sorry, I don't know what you mean by a 1:1 ratio. Both shots were taken of the same target, with the same lens at the same distance. The target filled the screen.

I don't know the answer to your question but they are not both of the same target. Could there be a difference in the size of the targets?

When you look at both of them at 100% magnification, you can see that the D7200 version is larger, so it shows more detail in the fine areas. The attached photo shows a section of both targets side-by-side in Photoshop, where both are at 100%.
Also, the bottom of the Photoshop screenshot show that indeed, the D7000 image is 4298 x 3264 pixels (~14 megapixels), and the D7200 image is 6000 x 4000 pixels (24 MP). Lots more data, so you can crop more or print bigger, and still have plenty of resolution.

This two pics are made under different condition.....more pix don’t mean better pics. The low pass filter was created to avoid Monroe effect. With low pass the sharpness is slightly softer in focus. Refurbished isn’t always a good solution, sometimes the refurbish something what doesn’t need to be touched.....I bought some used camera and was lucky. When I buy used I check shutter count, noise on body, buttons function, scratches.....

Do you really think that is the difference? Let me show you some more. I blew a portion of each up 1529% to get a good view of the edges. In these two blowups, the D7000 (3499) looks sharper to me.

Auto Spell check? Hate when that happens!
I think Moiré may be the term you’re looking for.

I noticed an immediate difference in sharpness going from the D800 to the D810.

No. The left sides are the same. Thanks for your interest.
Maybe they are the same.
They have different dates.

The D7000 test was made a year ago. The D7200 just this week. I don't think this should make amy difference.

Check for front or back focusing issues. Because of manufacturing tolerances, you can have camera and lens combinations that will front or back focus. Both cameras have AF fine tuning. Nikon recommends against using large amounts of AF fine tuning.
Are you using the .jpeg files out of the camera? Nikon cameras apply the Picture Controls to .jpeg files. They set the default sharpening very low. Go through all of the Picture Controls - standard, neutral, vivid, monochrome and boost the sharpening to level 6.

I think sending it back based upon conclusions from the test examples you have posted here does not make sense.
You have not even bothered to get your target image flat or on the same plane as the sensor. Two different charts, two different ages?, two different papers or printers maybe?, and two different sizes.
