Pear disease diagnosis?

Forgive me because I’m still new to pears, and I’m a bit confounded because I have other things planted that are supposed to be major disease magnets and they seem unaffected. So I’m not sure if I’m looking at “normal” seasonal appearance or disease indicators. These did get Revitalize multiple times and had dormant oil earlier in the season. Some of it looks like a nutrient issue, but some seems fungal. I had been sure Harrow Sweet had fireblight, but there is none of the characteristic wilting of ends. Help with diagnosis is appreciated.
