You need to post two photos where the camera is perfectly level and centre of the screen.Here’s a quick shot of an image from both TVs at a measured 7’ away. The image on the left is the 65” A9G and on the right is the Kuro 60” plasma. Even though the images don’t 100% show the differences, you can still see her head is larger on the Kuro 60”. Easier to see if viewed on something larger than a cell phone.
If you tilt the camera like you have with the Kuro photo, you get perspective distortion, which makes a comparison impossible. Look how much bigger the top of your Kuro looks compared to the bottom.
But looking at both photos, they are showing identical images. If your Sony is bigger, then the image as a whole is bigger. I think you're the victim of an optical illusion.
