There is a way to change the color of the display from the turquoise green/blue to a blue that almost matches the blue power on LED.
I have a pack of photographic professional lighting filters.
Vivid Colors #2
Bogen Cine FP206
#197 Alice Blue is the filter color that I used.
I measured and cut a section the same size as the display.
The film seems to have a "cling" property and stuck fast to the display.
There may be other tints that will work better, #197 was the closest thing that I had on hand.
I did not attempt to open up the BDP-1 to see if the film could be inserted from the inside, maybe later.
I hope that some will find this info useful!
