Does REST API doesn't allow to retrieve blob fields?

Hello everyone! I have difficult problem - when I try to get JSON data from ArcGis REST API by query command all is working fine, but one field is a type of blob (esriFieldTypeBlob) which really contains image. Unfortunately, the rest api don't return that field (is not listed with returned values). I've found that someone wrote that arcgis rest does not handle that type of field, but some sort of applications (ie. collector for arcgis) use it and show blob properly, so it's must be available. 

Is anyone know how to solve this issue? I'll be grateful for any clues. Thank you!

Maybe this Access data (Blob) | ArcGIS API for JavaScript 3.23  is a solution...

... or creating a replica into a FGDB and then use some Python as described here: How to extract feature service data with attachments enabled from ArcGIS Online — Esri UK
