The upgrade path from your plasma is an OLED TV, probably from LG.
And honestly it doesn’t sound like you’ve actually seen modern, not-cheap-Walmart expensive televisions these days. The color quality is incredible.
I’m not saying to run out and waste money on electronics, but there’s absolutely no way a 2011 plasma looks as good as a 4K OLED with all the modern processing technologies.
I've mentioned it above, those perfect colours make a movie less movie-like for me, because said perfectness makes me harder to suspend disbelief while watching said movies, which are displayed with perfect colors. I don't dispute that today's screens display colors in a more truthful way compared to my 2011 plasma, but that doesn't help with movie watching.
This is a very old discussion among movie buffs, that's why a few movie directors that can afford if artistically and money-wise still insist on filming on 35mm (even though today's digital recording devices are a lot more closer to "reality" compared to 35mm film). It's not only because of "hipsterism" or whatever one might think to call it.
