Apache mod_rewrite REQUEST_URI not matching pattern

Apache 2.4 on CentOS 7, on a cPanel/WHM remote server.

I want to get the Apache server's 404 response when a .jpg file is not found, instead of Rewriting to index.php which loads the entire web app.

Trying to do this in .htaccess.

#Trying to exclude jpegs:
RewriteCond %{REQUEST_URI} !\.jpg$
#And exclude these folders:
RewriteCond %{REQUEST_URI} !^/(folder1|folder2)/
#And rewrite everything else (commenting this results in regular Apache 404 responses for missing image files):
RewriteRule .* index.php [L]

When I try to load these URLs that result in 404, example.com/asdf.jpg, or example.com/folder1/abc.css, the RewriteRule still goes into effect, they get rewritten to index.php, and the CMS 404 page gets loaded.

When I comment the RewriteRule, then those two urls result in the lightweight Apache 404 response instead of the CMS 404 response.

Complete mod_rewrite section of .htaccess:

<IfModule mod_rewrite.c>
############################################
## enable rewrites

    Options +FollowSymLinks
    RewriteEngine on

        RewriteBase /


    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

############################################
## always send 404 on missing files in these folders

    RewriteCond %{REQUEST_URI} !^/(folder1|folder2)/

############################################
## never rewrite for existing files, directories and links

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-l
## test excluding .jpg from rewrite
    RewriteCond %{REQUEST_URI} !(\.jpg)$

############################################
## rewrite everything else to index.php

    RewriteRule .* index.php [L]

</IfModule>

Edit - here is the VirtualHost config:

Edit, I did rewrite trace6. It shows the .* rule being applied even though folder1 should not get the rule applied. I tried this on a virtual machine testing server and it works there, but not on this physical remote server.

Here are the first 13 lines of the trace:

It sounds like your rule is catching the subrequest when looking for the matching ErrorDocument. Try adding the NS flag to your rule.
