Full aray TV or Oled TV?

I looked for a 65 inch TV for my room and then I came across the full array TV from Sony for 1499 euro

when the gentleman from Media Markt showed me an alternative device, it ended up being the one to watch from Philips with Ambilight

Which was already available for 849 euro.

After a few days of use, however, I find the picture not very good and I have to say that I really wanted a bright and colored picture and therefore also wanted to get the full rate

ended up choosing the cheaper model for the time being

But what should go away now.

And since the Media Markt currently has a direct deduction campaign, I'm considering new ones

Sony Full array 65 inches only 1299 euro

Sony Oled 65 inches only 1699 euro

now my specific question

which is the better TV for a completely dark room and for Netflix and for gaming e.g. Playing sports

An OLED is already well suited for a dark room. Let the model names grow over there. I assume it's about the AG8 and the XG90?

Oled65b97

At Media Markt for 1999 euro

And I think that's the Xg95

But I really want the TV to last at least 5 years from the picture, but the oled has problems with this shadow on the YouTube button after a while and so or not?
