Question about Hoya HMC UV(0) Filter

Different model series, different coating. However, the designations here do not match the pictures at all. It's not right at the back and at the front. The picture shows a Skylight filter, but according to the designation it should be a UV filter. I would check the manufacturer's website: https://hoyafilter.com/ For pure protection, a Protector filter is sufficient anyway (if at all). UV and Skylight are superfluous in the digital age.
