was checking through Dpreview sample pictures of XT4
a picture caught my attention, 



Although they call it a velvia simulation, there's virtually no details in reds and they are oversaturated... I don't think Velvia would yield such a result

Indeed, I find the velvia film simulation horrible (on my X-T1 and X-T20 though, never tried a X-T4).

I don't think that Velvia was ever a preferred choice for flowers. Velvia creates extra punch and that just not what you need with flowers.
