thx. if you could copy/paste a snippet to show an example of the service metadata too, that'd be really helpful.

"fields": [
    {
      "name": "OBJECTID",
      "type": "esriFieldTypeOID",
      "alias": "OBJECTID",
      "domain": null
    },
    {
      "name": "Shape",
      "type": "esriFieldTypeGeometry",
      "alias": "Shape",
      "domain": null
    },
    {
      "name": "STATE_NAME",
      "type": "esriFieldTypeString",
      "alias": "STATE_NAME",
      "length": 25,
      "domain": null
    }
]

I have cut out a lot of fields, but included the ones I think were relevant:

"fields":[
    {"name":"floor","type":"esriFieldTypeString","alias":"FLOOR","length":20,"domain":null},
    {"name":"geometry","type":"esriFieldTypeGeometry","alias":"GEOMETRY","domain":null},
    {"name":"company_name","type":"esriFieldTypeString","alias":"COMPANY_NAME","length":50,"domain":null},
    {"name":"objectid","type":"esriFieldTypeOID","alias":"OBJECTID","domain":null},
    {"name":"st_area(geometry)","type":"esriFieldTypeDouble","alias":"st_area(geometry)","domain":null},
    {"name":"st_length(geometry)","type":"esriFieldTypeDouble","alias":"st_length(geometry)","domain":null}
]

It looks like I was able to fix the problem on the ArcGIS Server end:

Publishing the service with only Mapping capabilities publishes the attributes with all caps (like the layer in ArcGIS Desktop). I originally had KML and Feature Access enabled as well, which caused the layer to be published with lower case attribute names, which messed up the symbology, as well as some of my esri-leaflet code.

Not retaining the symbology for the service still seems like a bug though.

thats really weird.

glad to hear its just a curiosity at this point, but i'll still find time to try and trap the undesirable behavior here.

My guess is AGS does this for compatibility sake for KML or Feature Access. Maybe capitalization isn't supported in one of those standards?

PRs welcome, I don't have plans to work on this one though.
