I have recently purchased a new 4K/UHD TV. The TV is a Digihome 55", model: 55304UHDSM. As a budget (I believe vestal based) set there is unfortunately barely any info online about it so I don't know if the issue I have is common on these. Anyway, while I am generally really pleased with it in terms of general colour, detail and overall PQ, the set does seem to suffer from fairly noticeable backlight leakage or bleed at the four corners of the panel.
I wouldn't say it is terribly noticeable generally and not obvious at all on lighter scenes, but on scenes where much of the image is dark/black the four corners do appear noticeably lighter and on such scenes once you have seen the issue you unfortunately cannot easily un-see it.
Anyway, the purpose of this thread is partly to determine how retailers view backlight bleed, is it considered as a defect and thus the set can be swapped for a replacement? However, assuming the retailer (Coop Electrical) does agree there is a defect, what are the chances of a replacement having exactly the same issue? As I’m sure once can appreciate a 55” TV requires a fair bit of work to repackage and reinstall the new one and it would be incredibly annoying if the replacement did the exact same thing.
Might I be better trying to get a partial refund for the issue and just accepting that this model of TV is going to have some degree of backlight bleed regardless?
Finally, are there any actions I could take myself to minimise the visibility of backlight bleed? Is the amount of bleed related to the backlight level? E.g. if I used say a backlight level of 50% instead of the current 100% would the reduced light intensity hide the bleed?
As always, any advice greatly appreciated.

by comparison a little bit of goodwill in a one off small partial refund or even just a credit against a future purchase (which I would have been equally happy with) to encourage repeat trade costs them virtually nothing in real terms, yet goes a long way with the customer so it’s puzzling why some retailers are stupidly adverse to offering them.
