Thoughts about Samsung G6? (G61SD)

Hi there!
I was able to order the Odyssey OLED G6 G61SD 240Hz, for 400 euro. The sales man in the store, showed me the monitor, compared to an OLED monitor which had blank finish and an LG panel. The colors looked liked they popped way more, on the LG display, and the Samsung didn't seem to make as great deep blacks.

I do alot of different things on my pc, mainly gaming but also photoshop work and just everyday use. I suddenly started to doubt my decision, I want an OLED display, that can bring the colors on my screen to a new level, instead of my old IPS display.

So i wanted to hear some opinions on here - what do you think, will this leave with a good OLED impression, and how do you feel considering the price?
