I'm curious about that too, but I don't have one of those meters yet.
I have 2 left my displays are good but oled would be nice to have seller has not replied on aliexpress about usa ship.
I considered this too until I came to the line in the description:
"Since the display area of the new OLED is larger than the original VFD,the front frame of the multimeter should be cut out alittle"
I'm not wild about cutting up the front panel so I found a new, original replacement display on ebay from a seller in Australia. That worked out great!

I would do it anyway.

I can make a new lens with a laser to cover the mods and make it look noice.
