It's 1:1 as it should be with an original system, the only time it may not is with some games if you're using multiple graphic filters it can slide on the frame rate slightly, much like a frame skip you'll get off an emulator.
The pixel effect you're thinking is a negative on the SNES, that's up to the TV size you have. Any system will do it, and all are equally noticeable too because it's taking the raw feed and displaying it with perfect sharpness you'd expect on a computer LCD/LED screen from an emulator with no filters active so it's just very very crisp.
The german stuff (PAL) it's possible it could be running off since they're made for 50hz not 60 which is NTSC so you can get speed issues or at least the music will run at the wrong pacing. I've had the PAL Parodius cart in the past and it would run the music a bit quicker, maybe the game too, can't compare now as I just have the Famicom cart, but it also did cut off the score (but not the options bar) at the bottom partly.
I'll say this much if you do Gameboy, I'd suggest if you are that afraid of chunky and blocky, play it in the original aspect ratio in a box or you'll get really annoyed by it fast. GBA games look the blockiest due to the higher color/depth of visuals it has over earlier 16bit consoles and 8bit as it falls in line but far worse in your impression of the SNES output.
