Yes, I have a large number of people in a circle of extended family and friends back in England, including two who served in the military, and none of them have lost one iota of respect or friendly feelings towards Harry.
Samantha Markle has replied to someone on her Twitter page, saying she knew nothing about any show, nobody's spoken to her about it and how ridiculous it was that the BBC should do a show about her family, lol.
So, unless she's lying through her back teeth, (possible, with her behaviour since last year) it would be rather odd for Channel 4 to say that such a show is in the works without Meghan's main prosecutor being centre stage.
