Hi @Adny Whilst you do not mention the specific Q90 model (as there are different ones) ,QLED provides a much wider colour range which enables the colours to "pop" more so would be the better option if budget allows. Crystal UHD (The TU7020) though does have a feature called Dynamic Crystal Colour that provides a large number of shades.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
