Apple Watch with Tattoos

I know that this has been discussed a lot on here, but it was a few years ago. My Apple Watch will not stay unlocked on my wrist with a tattoo, so per recommendations I turned off wrist detection. Some say it doesn’t work because of the optical sensor but what I don’t understand is that it can still take my heart rate while working out, or when manually opening the heart rate app. Do you think it’s just a software issue that it won’t stay unlocked with wrist detection on?
