Apple Watch 9 - Is it being sold with known issues?

I collected an apple Watch 9 41mm on Saturday 11 November 2023 at the Mall of Africa store. I have since discovered that the brightness is very low in low light conditions, even with the device brightness turned to full. The Apple discussion forums on the internet are full of stories of this problem with the Watch 9. Seems to be a hardware issue and not software related, I emailed iStore this morning about this issue but they failed to respond. It seems to me that the iStore is selling products that have a known issue, if the internet complaints are to be believed. iStore must respond to my complaint and take back a clearly defective device. A full investigation is required to determine if iStore is knowingly selling products with known issues.
