Bad Omen Bottles

So, correct me if I'm wrong but is there much point in having the different levels of bad omen when all you need is a level 1 to active both ominous trials and raids? The different levels only affect the length of time trial omen lasts for and how long Hero of the village lasts for and that's basically it right?

If I have loads of bad omen 1 bottles and just used those over and over again for trials and raids there'll be no actual effect on the difficulty right? I think that the higher levels affect the number of waves in a raid but only by 1 and even then its barely any difference.

e.g. I did a raid earlier with bad omen V expecting it to be a really difficult raid and all I got was 1 evoker and the raid was over, just like that. There was only like 5 waves, if even that.

I don't mean to say this dissing the new mechanics, I'm just confused as to what the point is of having the different levels of the effect?

(mainly play on Bedrock Realm btw)
