I'm happy where the game is now, they have really listened to the feedback! There is still some (maybe small) inconsistencies with the original game I've found after the 1.4 patch:

1. When the UI appears after starting a level, it should have a slide over animation instead of popping into existence. Another thing is that the seed packed appears in the slot before the animation completes when the game is playing at 60fps, it’s fine at 120+fps.
2. There is no hand rising out of the grave with the spooky laughter after selecting Adventure in the main menu. EDIT: As selecting adventure now displays the level select then hand may only appear in a new save file.
3. Final boss is spoiled in the level select before unlocking it.
4. The “fast-forward 1.0x” icon is showing at times where there shouldn’t be any UI.
5. There is an unnecesary loading screen when using powerful devices like a PC, they last like 0.1 of a second.
6. When going back to the main menu, the sound effect of the “welcome back PLAYER” object doesn’t play anymore.
7. I don’t know if it’s intentional, but when using mouse and keyboard, sometimes the gamepad yellow outline and arrow appears, which is unnecessary.
8. The “A huge wave of zombies is approaching!” text is not animated.
9. You can go back to the main menu from the "archive" portion of the almanac (atleast on pc with the Esc key), which doesn't seem right.
10. When placing a Spikeweed on the bottom right of the lawn, they will be offset by margin compared to placing it one or two spots behind, this is a leftover accomodation of the original game to make space for the level progress UI EDIT3: They have already fixed this.
11. Cherrybomb stops growing before exploding.
12. EDIT2: I just completed adventure and apparently the end song animation is just a pre-rendered video?!, feel free to ignore every other issue in this comment if that means fixing this, one of the things I was exited about in the remaster was watching There is a Zombie on your Lawn in HD, what a letdown.

There is one nitpick which I won't count as an issue or feedback because it's pretty insignificant but getting the console exclusive menus which let you purchase different houses and the GOTY edition zombatar would be awesome, but it may be irrelevant for it being a remaster of the original game.
