Inconsistency in Image Size with Laravel Media Library's Responsive Images

[daalvand]

Two Issues with Laravel Media Library

First

The first issue is related to the size of the images. I have observed that my original image, with a size of 111kb and dimensions of 1200x695, has a larger size (178kb) in responsive images with the same dimensions.
Even when the responsive image's dimensions are smaller (839x486), the size is still larger (122kb).

Here is the original image information:

Here is responsive images information:

This issue with the size makes it better to use the original image instead of the responsive one (actually, responsive images are useless).
Is there a way to resolve this issue?

second:

The second issue I have encountered is that I observe that two images with the same dimensions, one with one responsive image and the other with six responsive images (is it depend on image size?).

Here is an example:
first one has one responsive image:

second one has six responsive images:
