This was exactly my experience on the TV end. Prior to getting my LG OLED I had just experienced my family members bargain price 4k panels and did not think 4k was worth it. Then at my work we upgraded all of our QC tvs to LG OLEDs and the lead of team gave us a demo. The contrast and color difference in HDR on the top of the line OLED panel was amazing. Bought one a couple months later. My wife indulged me, but didn’t really care. Once it arrived and we watched a movie on it she was 100% sold. We both consider it one of our best big ticket purchases. Also told my coworkers about it and a few purchased some in the years following. They all love them as well.
The only complaint I have about mine is how fire appears in HDR. The color is washed out and has some ghosting in dark scenes where it is the brightest object. Not a huge issue most of the time though.
Also for OP, IMO high quality 4k OLED panel is only worth it if you watch a lot of cinematic content in that is produced in SDR or HDR. if you are just watching sports, news, or sitcoms most of the time I would not consider it worth it. I have advised my father against getting one for this exact reason.
👆This. It’s not going to affect this particular bike’s value too much in either direction. If you think the paint prep is worth the effort then go for it!
From a practical standpoint, you might want to consider at least cleaning up any exposed steel and applying a little clear coat.
