   Ok, I went and copied https://github.com/seperman/deepdiff/blob/master/deepdiff/colored_view.py to my project.
   From there I modified it with a new flag hide_unchanged_root_keys that is used in _colorize_json:

       def _path_is_dict_root(self, path: str) -> bool:
           """Check if a path is the root of a dictionary."""
           return path.startswith("root['") and path.endswith("']") and path.count("'") == 2
   
       def _colorize_json(self, obj: Any, path: str = "root", indent: int = 0) -> str:
           ...
           if isinstance(obj, dict):
               ...
               for key, value in obj.items():
                   if (new_path in self.diff_paths and self.diff_paths[new_path][0] == "added"):
                       ...
                   else:
                       new_value = self._colorize_json(value, new_path, indent + 1)
                       if not (
                           self.hide_unchanged_root_keys
                           and self._path_is_dict_root(new_path)
                           and new_value == "{...}"
                       ):
                           items.append(f'{next_indent}"{key}": {new_value}')
               ...

   Works for me, but the detection of whether I am on the root feels ugly.

   Facing the same issue,

   It would be nice if there was a built-in way to only show the changed items rather than all of them.

   yes - working with @Arshadwaqas115 and would love to see an "Ultra Compact" view that shows changes only

   e.g. working from you example:
   https://zepworks.com/deepdiff/current/colored_view.html#colored-compact-view

   Current Compact View

   from deepdiff import DeepDiff
   from deepdiff.helper import COLORED_COMPACT_VIEW
   
   t1 = {"name": "John", "age": 30, "scores": [1, 2, 3], "address": {"city": "New York", "zip": "10001"}}
   t2 = {"name": "John", "age": 31, "scores": [1, 2, 4], "address": {"city": "New York", "zip": "10001"}, "new": "value"}
   
   diff = DeepDiff(t1, t2, view=COLORED_COMPACT_VIEW)
   print(diff)
   
   {
     "name": "John",
     "age": 30 -> 31,
     "scores": [
       1,
       2,
       3 -> 4
     ],
     "address": {...},
     "new": "value"
   }

   Proposed Ultra-Compact View

   from deepdiff import DeepDiff
   from deepdiff.helper import COLORED_ULTRACOMPACT_VIEW
   
   t1 = {"name": "John", "age": 30, "scores": [1, 2, 3], "address": {"city": "New York", "zip": "10001"}}
   t2 = {"name": "John", "age": 31, "scores": [1, 2, 4], "address": {"city": "New York", "zip": "10001"}, "new": "value"}
   
   diff = DeepDiff(t1, t2, view=COLORED_ULTRACOMPACT_VIEW)
   print(diff)
   
   {
     "age": 30 -> 31,
     "scores": [
       3 -> 4
     ],
     "new": "value"
   }
