Rare Razer Blade Stealth Late 2019 Mercury White with GTX 1650

Hi, I recently bought a rare Razer Blade Stealth Mercury White Late 2019 model secondhand from eBay. Seller claimed this is one of the few Mercury White models that has a gtx 1650. I was a bit sceptic. I thought maybe some part of windows was edited to make it look like it has a gtx 1650 gpu or a motherboard from the black late 2019 variant was replaced. Upon receiving it, it has the 65w power adapter. I opened the back cover and saw it has the dedicated gpu chip. It seemed legit. I powered it up and checked device manager and it does show there are 2 gpu's. I tested the discrete gpu through furmark and it wasn't utilizing the discrete gpu at all even if I force nvidia and windows to use the discrete gpu at all times. Gpu-z shows 0 mhz for both core clock and mem clock. I was starting to think that maybe this unit was a scam. I have another razer blade stealth late 2019 black 4k version which was the gtx variant. I saved a copy of its bios and flashed it to this white variant. To my surprise it worked and now the discrete gpu can be fully utilized. I ran firestrike and the score is pretty good as well. Razer Synapse now detects my system as the black gtx variant. My conclusion is, razer indeed sold a few units of the blade stealth late 2019 mercury white with gtx gpu's and they intentionally disabled it. The solution to this is to flash a bios from the black gtx variant and you are good to go. My question is, does anyone have a unit like me? How rare is this? as proof, I'm attaching photos of the serial number in both the box, back cover and BIOS. Also, should i upgrade my power adapter to the standard 100w? I could imagine the 65w included is not enough for gaming.
