No the blooming is not evenly remotely as bad as seen in the video, the same youtuber Andy in his later videos seems very impressed with the black room performance n blooming control , he even speculates that the VA version might not be any different.
BOE ADS panel have native contrast of 2000:1 while the VA version due to ultra viewing angle is about 3600:1 so if one makes a simplistic assumption then the VA version will have 1.6 times better blooming n contrast but this is a not a significant difference and cannot be ascertained in real world usage. I was fortunate enough to compare my QN90A with the Sony X90J (VA,6000:1 ratio) side by side n Samsung clearly had better blacks n blooming control.
As
@OM_2K19 says that blooming is inherent to LED tech irrespective of the panel used. Samsung Algorithm combined with Mini LED + 600 dimming zones helps immensely with black level. Despite there crappy customer service the Samsung flagships remain the best LED out there.
Samsung India as things stand are not offering you a refund ( No 50 "in the stock either) and instead you have a Samsung coupon which I believe comes with an short expiry date so your options are rather limited. You could perhaps consider last year's Q90T (VA panel but no mini LED n limited dimming zones) or this year's QN85A n save some money in the process without losing much on PQ. Look if your Samsung coupon had a year long validy then I would have advised you to wait for next year's model.
