Take this how you like.
The uhd50 was taken with a note 8 & the ht3550 was from a Galaxy s10.
Also white screen on the uhd50 & grey screen on the ht3550 not a fair comparison .
Like everyone keeps saying yes its much sharper on the uhd50/51.
but too me the colors the flesh tones , natural colors looks way better on the ht3550.
but again the uhd50/51 gave it a pop on the colors i tried different settings.
i'm no expert so i'm not getting into this.
To me the uhd50 just had too much red on skin tones i'm sure that could of been calibrated" again no expert here ".
the ht3550 skin tones looks awesome , but the missing details just annoys me & the fan noise even on ECO,
The fan loves to ramp up every once in awhile , a problem to me but probably not to other .
I do have the projector 3 ft on top of me .
The uhd50 i did have to return it like 2-3 times till i got one with no buzz, it was really quiet .
This is also on netflix with hdr.
Also take this as you like this was taken a few month apart different phones /screen .
Not sure why the color looks so red online but downloaded the picture doesn't look like that.
Top uhd50 bottom ht3550
Won't be going back to the uhd50/51, because of buzz noise/the light border around the screen. I'll probably go with uhd60/65/epson 4010/5040
Not trying to tell people not to get the ht3550 , to me i guess it all depends on what you like, Black level contrast & color accuracy ht3550.
Sharpness details, that color pop not sure what else to call it , uhd50/51.
