I'm glad to see an OLED owner that is not in complete denial of screen burn in. My choice in what 4K tv to buy was made by still ongoing burn in issues. I've had it on my Panasonic plasma tv. Not from static images but because so many tv programs were still 4:3 with black borders. Burn in is simply uneven wear, so when there finally was a widescreen program, the sides that were normally dark were now extra bright. It took years for that to go away after all tv converted to 16:9. Black levels got worse over time as well, colors dull. Plasma and OLED degrade over time, if unevenly by static images, hud elements, tag heuer logo between races, it's going to show after a year.

I would go for the pro. I use it on a 1080p tv, but the faster loading times are already worth it. Plus on a base ps4, GT Sport will already take up a huge chunk of the 500gb hdd space. You only get 400 or so for games and GTS takes almost 100GB nowadays, and requires the same in free space for patches.
