Yes and no.
Like I said, you're not going to replace a mid-range meal with a 100 calorie or 800 calorie meal and not realise that you're skewing your meal values. We know what "a small meal", "a medium meal" and "a blowout" look like.
So while it's best to spread your calories out a little over the day, you will do that pretty much naturally. You don't need to know that the 120 calorie recommend bread that you replaced with another brand is actually only 100 calories. That's inconsequential for that one meal. And the actual value is reflected in the whole day total at the bottom, so that's keeping you on track.
But also, yes, if someone eats 1200 calories in one single meal once per day, they will lose weight the same as someone who eats three 400 calorie meals across the day. This is well proven.
HOWEVER, someone eating one large meal is much more likely to pig out due to hunger at other points of the day, and therefore find themselves not actually having just the 1200 calories. They'll be grumpier, unsatisfied, constantly hungry, and lethargic.
The "weight loss" is about the numbers. The success of sticking to a weight loss plan can be about balanced and planning and spreading your calories out.
With your meal today, how much over/under was it to the recommended values? I suspect you'll find that it's not significant - just the banana difference. If you are allergic to the suggested fruit, and you want to ensure you're eating "as per the plan", then eat a different fruit instead of leaving it out entirely. :)
Certainly spark can take or leave your suggestion, and it's always great to offer them when you see value to be added.
But based on Spark's approach at the moment of weekly averages, I really don't think they're likely to focus on meal spreading of calories. As hopefully made a bit more clear, that value isn't something that's actually important to know.
Total daily calories is king. Nothing else really matters.
