Good question.
No, the opposite. The market right now is dominated by hiphop/rap, trap and 808-based beats (which is cool because there is a time for every sound), but for Cheiron pop lovers like most people in this forum the current market lacks 'real' melodic pop songs.
If you look at the Billboard Hot 100 Top 10 this week the only song that falls under this category is 'Blinding Lights' by The Weeknd (by Max, funny enough) and that is even a melodic pop song disguised as a cool, retro, 80's electro-pop song.
'Pure pop' is an expression that I've seen used many times in this forum and IMO it is a term covering melodic, catchy pop songs - maybe even glossy, bubblegum-ish pop songs and productions, which are generally not regarded as 'cool' in this day and age.
So my point is that the Ava Max album stands out in 2020, because it is a whole album with these types of 'cheesy' pop songs, which are rare these days.
Strong melody never gets out of fashion, only dressing changes. That's what Max is good at, turning not so strong song and production like Weekn'd one you mentioned into a hit. The only thing that sets that song apart from the average is the strong melody in the pre-chorus and chorus.
So, pop is strong melody + specific 'pop' dressing. Not more not less.
